Untwisted
=========
What is untwisted?
A library for asynchronous programming in python.
Despite of the above statement being true it doesn't answer the question entirely.
Untwisted is a different approach to solve the problem of implementing networking applications.
Untwisted architecture makes it simpler to handle internet protocols, consequently it is easier
to implement applications that run on top of such protocols.
Untwisted supports asynchronously dealing with sockets, file descriptors while spawning threads to
perform other jobs. It is possible to talk to a process using a thread based approach or a unix file
descriptor while waiting for socket's events. Untwisted basically solves the problem that some python
libraries like pexpect and twisted proposes to solve in a neat and powerful way.
Untwisted is extremely modular, applications that are implemented on top of untwisted tend to be
succint and elegant. Untwisted has an impressive performance when compared to other python frameworks.
You may be wondering right now why you would endevour to learn a new python asynchronous framework once
you have spent so many hours trying to learn asynchronous programming in python with other frameworks.
One of the reasons to learn untwisted framework is the fact that you'll spend some pleasant hours
understanding untwisted and some minutes implementing complex applications on top of it. Another reason is
that if you like clean, consistent and high performance code then untwisted is for you.
### Web Server
A basic rapidserv web application.
~~~python
from untwisted.plugins.rapidserv import RapidServ, core
app = RapidServ(__file__)
@app.request('GET /')
def send_base(con, request):
con.add_data('<html> <body> <p> Rapidserv </p> </body> </html>')
con.done()
if __name__ == '__main__':
app.bind('0.0.0.0', 80, 50)
core.gear.mainloop()
~~~
### Echo Server
This neat piece of code implements a basic echo server.
~~~python
from untwisted.network import Spin, xmap, core
from untwisted.iostd import create_server, ACCEPT, LOAD
class EchoServer(object):
def __init__(self, server):
xmap(server, ACCEPT, lambda server, con:
xmap(con, LOAD, lambda con, data: con.dump(data)))
if __name__ == '__main__':
EchoServer(create_server('0.0.0.0', 1234, 5))
core.gear.mainloop()
~~~
###
### Chat Server
This simple chat server permits clients to connect through telnet protocol,
pick up a nick then start chatting.
~~~python
from untwisted.network import core, Spin, xmap
from untwisted.iostd import create_server, ACCEPT, CLOSE, lose
from untwisted.splits import Terminator
from untwisted.tools import coroutine
class ChatServer(object):
def __init__(self, server):
xmap(server, ACCEPT, self.handle_accept)
self.pool = []
@coroutine
def handle_accept(self, server, client):
Terminator(client, delim='\r\n')
xmap(client, CLOSE, lambda client, err: self.pool.remove(client))
client.dump('Type a nick.\r\nNick:')
client.nick, = yield client, Terminator.FOUND
xmap(client, Terminator.FOUND, self.echo_msg)
self.pool.append(client)
def echo_msg(self, client, data):
for ind in self.pool:
if not ind is client:
ind.dump('%s:%s\r\n' % (client.nick, data))
if __name__ == '__main__':
server = create_server('', 1234, 5)
ChatServer(server)
core.gear.mainloop()
~~~
### Spawn Processes
The example below spawns a python process then sends a line of code.
~~~python
from untwisted.expect import Expect, LOAD, CLOSE
from untwisted.network import core, xmap, die
def handle(expect, data):
print data
expect = Expect('python', '-i', '-u')
xmap(expect, LOAD, handle)
xmap(expect, CLOSE, lambda expect: die())
expect.send('print "hello world"\nquit()\n')
core.gear.mainloop()
~~~
